We present the first dataset of spatially resolved velocity maps of weakly lensed galaxies. All information can be found in "The first shear measurements from precision weak lensing, Gurri et. al. 2020, MNRAS". 

The sample represents an unbiased compendium of isolated/central galaxy halos that lay in close projection to a lens and that are expected to be lensed. All galaxies are sources at redshift ~ 0.1 - 0.15 (far enough for the lensing signal to be large and the source density high enough for targets to be common, but not so far as to be un-observable with a 2.3m telescope) and have impact parameters ~ 10s of kpc (which balances decreasing shear with increasing covering fraction as a function of radius), and predicted shears ~ 0.001 - 0.02. Typical source sizes are ~ 5''; i.e., large enough to be resolved under typical seeing of 1 - 2'' (FWHM) at Siding Spring Observatory, and small enough to fit within the 25'' X 38'' WiFeS field of view.

NOT_IN_PAPER_X.zip contains all the data for all the galaxies observed which are not included in the Gurri et.al. 2020 analysis, 3 files include all galaxies.
VEL_ONLY_NOT_IN_PAPER_ALL.zip contains only the final velocity fields for all the galaxies observed which are not included in the Gurri et. al. 2020 analysis.
IN_PAPER.zip contains all the data for the galaxies included in Gurri et.al. 2020.
VEL_ONLY_IN_PAPER.zip contains only the final velocity fields for the galaxies included in Gurri et.al. 2020

Each system is contained in a directory of the shape GGLXXX_XXX.

GGLXXX_XXX.fits contains the velocity map after reducing and processing the data.

The dimensions are:
# -- NAXIS1 [0.5 * arcseconds]                                                  
# -- NAXIS2 [arcseconds]
# -- VALUE  [km/s]

Raw data for the galaxy can be found in the raw_data directory.
.p11.fits files are reduced data for the galaxy
.p08.fits files are reduced data for the standard star
r denotes red arm
b denotes blue arm
